Відповідь:

6) 4 8/15 - 6 2/3 : 1 2/3 = 68/15 - 20/3 * 5/3 = 68/15 - 4/1 * 1/1 = 68/15 - 4/1 = 8/15

7) 5 3/7 : 19/7 + 8 5/7 = 38/7 * 7/19 + 8 5/7 = 2/1 * 1/1 + 8 5/7 = 2/1 +8 5/7 = 10 5/7

8) 7 1/3 - 5 6/7 : 41/14 = 22/3 - 41/7 * 14/41 = 22/3 - 1/1 * 2/1 = 22/3 - 2/1 = 16/3

9) (3 7/8 - 2 5/6) : 1 1/4 = (31/8 - 17/6) : 5/4 = 25/24 * 4/5 = 5/6 * 1/1 = 5/6

10) (7 5/8 - 5 3/4) : 5/14 = (61/8 - 23/4) * 14/5 = 15/8 * 14/5 = 3/4 * 7/1 = 21/4

11) (4 3/8 - 1 1/4) : 15/8 = (35/8 - 5/4) * 8/15 = 25/8 * 8/15 = 5/1 * 1/3 = 5/3

12) 1 3/4 : 7/8 + 8 5/7 = 7/4 * 8/7 + 8 5/7 = 1/1 * 2/1 + 8 5/7 = 2/1 + 8 5/7 = 10 5/7

13) 1 7/8 : 3/4 + 3 1/5 = 15/8 * 4/3 + 16/5 = 5/2 * 1/1 + 16/5 = 5/2 + 16/5 = 57/10
